Can carriers and aux replenish their own missile supply?

[Raptor34]

From what I'm understanding but haven't tried out, they could do it by reloading a frigate with the appropriate launcher docked to them and then transferring the missiles back. But are they able to directly build missiles for their own launcher?
I'm wondering if carriers and aux ships with closed loop are the ultimate missile boats. Or well, a Guppy could work too, but the smaller missile capacity of S ships makes it more of a pain.
